When will see next price cuts for the PS3 and 360 in the USA?

[Rock_on_2008]

I wonder if anyone knows when the price cuts will appear in the USA for both the PS3 and 360? How much will the price cuts be? Say $50 across the board on all models? I know there will be no Wii price cuts for this year due to supply struggling to meet up with demand.

Please tell me when the price cuts will appear.
